Berner, D.K.Sauerborn, J.Hess, D.E.Emechebe, A.M.[The role of biological control in integrated management of Striga species in Africa]The role of biological control in integrated management of Striga species in Africa

Striga hermonthica causes serious crop yield losses in West Africa. Hand pulling, an effective method for the reduction of light infestations, might be encouraged if farmers could use this weed as livestock feed. This study evaluated the chemical composition and the voluntary intake and digestion...

A regional Sorghum Head-Bug and Grain Mold Trial was conducted in 1996 and 1997 by WCASRN in, respectively, 15 and 13 research stations in ten west and central African countries. Empirical relationships between weather factors and head-bug damage on the one hand, and between weather factors and g...

Relationships between weather, headbug and mold damage on sorghum grains]Sorghum headbugs and grain molds in West and Central Africa: II. Relationships between weather, headbug and mold damage on sorghum grains

Resistance to anthracnose, caused by Colletotrichum graminicola, in sorghum was identified through field screening at two locations (Samanko and Longorola) in Mali. The occurrence and progress of anthracnose were monitored on 19 sorghum lines plus resistant and susceptible checks in the 1996 to 1...
